<i>Arsenophonus</i> Interacts with <i>Buchnera</i> to Improve Growth Performance of Aphids under Amino Acid Stress

Abstract

The obligate symbiont Buchnera can synthesize amino acids for aphids. In this study, we found that a facultative symbiont, Arsenophonus , can help improve aphids’ growth performance under amino acid deficiency stress by changing the relative abundance of Buchnera and the expression levels of amino acid synthase genes. This study highlights the interaction between Arsenophonus and Buchnera to ameliorate aphid growth under amino acid stress.
